I have a disc bound notebook that allows me to refill my pages. I also follow the approach that
Shawn demonstrated. Everything stays in OmniFocus but I move three tasks and one big rock project to my notebook. I already know what I want to do by looking at the notebook. I do to make the next decision after completing a task.
I will open my projects view to go in depth into a big rock project but that’s about it. The more time I spend outside my task manager, the more time I am a actually working on a project.
For structure, I printed out my own planner pages that fits me. It took a little experimenting for me to get my own structured planner pages but it works for me. I took inspiration from other planner pages until I found what I needed.
See how the FFP works for you. Then you might get inspired to make your own structured planner using a 3 ring binder or a disc bound notebook.
